is often diagnosed during a routine visit to your doctor. Blood pressure is measured using a cuff around your arm and a device called a sphygmomanometer. Your doctor may ask you to sit quietly for 5 minutes before checking your blood pressure.

For most people, it takes more than one high blood pressure reading to diagnose high blood pressure. If your blood pressure reading is high, a second measurement will be done a few minutes later. If your blood pressure is still high, you will probably be asked to come back for repeat blood pressure checks. High blood pressure diagnosis will be made when you have readings over 140/90 mmHg during 3 separate visits.
Sometimes people become anxious at the doctor's office. This may result in a higher than normal blood pressure reading. You may be asked to measure your blood pressure at home or in another location.
In some cases, you may be asked to wear an ambulatory blood pressure monitor. This device measures your blood pressure regularly throughout the day as you go about your activities. It is usually worn for 24 hours, even while sleeping.
